Diffusion Tensor Imaging has been known for quite some time now, but I fear that it might be just another experimental tool

that never goes into use in clinical practice, even though it is very promising. My guess is minimum 10 years before they use it in a clinical setting and only severe cases will benefit from this.

Just like the SPECT scan which is usefull in diagnosing some forms of PCS but it is almost never used for this purpose.
